libical 2.0.0 release checklist

[Ken Murchison]

After reading RFC 5545 again (section 3.3.11) I think the clients are to 
blame for some of this.  It appears that commas are always supposed to 
be escaped in TEXT values, unless the comma is splitting multiple 
values.  Apple clearly isn't doing this in their X- property.

I'm thinking we should be liberal in what we except, meaning that for a 
known single value property, we should accept both escaped and 
un-escaped commas.  In the case of a multi-valued property like 
CATEGORIES, we should split on any un-escaped comma.  When outputting 
iCalendar data we should follow the spec.
